[QUOTE="Long Time Long Ranger, post: 356006, member: 505"] I was just speaking from a velocity standpoint. There are many other factors to consider. I have two standard 338 Lapuas with 26" barrels for hunting weight carry guns and a few of most the other big 338's. Great cartridge and I enjoy shooting them. I was just pointing out that velocity makes a difference in long range hunting because the wind is so difficult to judge across canyons and the more velocity, the less wind drift. All the big 338's hit with a lot of force at long range. That is why they are by far the best choice at elk size critters. If I am shooting way long I typically go with the extra velocity of my 338-378 wby. All will easily kill stuff at the 1200 yards backyardsniper mentioned. If he wants to go the 1600-1800 yards I would not go below a 338-378 wby and get all the velocity I could get. This is my opinion on the brass. When I tried to push my lapuas up toward 338-378 wby velocities the brass didn't last very long so I dropped back where the lapua should shoot and lapua brass has excellent longevity. By the same token when I drop the 338-378 wby down toward lapua velocities the wby brass has very good longevity. My favorite 338-378 wby shoots the 300 smk at 3058 fps out of a 28" barrel, the 250 at 3310fps, the 225 at 3465fps and the 200 at 3600 fps. At these velocities I get about 5 shots per brass. I can get my lapuas within about 150 fps of these velocities and get about 5 shots per brass. I can drop either down 100 fps and shoot the brass many times.
